Nitro Pro 11 Download / Activation Issues

[Brianne B]

I recently had to uninstall NitroPro 11 and I am now unable to re-install 11 and when I try to activate 12 or 13 I receive an error message.

Hello @Brianne B,

Thank you for reaching out to us through our Community Forums!

To further assist you, could you please provide the serial number of your Nitro Pro you are having issue activating?

Also, please provide a screenshot 'About Nitro Pro' that shows the exact build.

You can find this out by clicking on 'About Nitro Pro' under the Help tab (format is 13.X.X.X, e.g. 13.2.3.26) or you can go to Control Panel > Programs and Features.

To send them via private message, hover your mouse on top of my name 'AllainU' and select 'Message'.

This matters because our business installers are different from the online ones.

Thanks and I am looking forward to hearing back from you.

Hello @Brianne B,

Thank you for the private message.

Please be informed that '-22 Error - Wrong License Number' and 'The serial number entered does not exist' means the serial number you are trying to activate is for a different version of Nitro Pro. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 11. We then activate it using your serial number. Kindly follow these steps:
 
1. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine.

2. Please clear all your downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

3. Download your Nitro Pro 11 using these offline link/s:

x64-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x64.msi 
x32-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x86.msi

If you are unsure if your machine is using 32 or 64-bit, please refer to this link: https://kb.gonitro.com/knowledgebase/#/search/64/000003790 

4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number.

Cheers!
